PLANING-MACHINE.

1,032,806. Specification of Letters Patent. t nt July g- Applicationfiled July 3, 1908., Serial No. 441,865.

To all whom it may. concern:

Be it known that I, A rHUR BATEs, a subject of-the King of GreatBritain, residing at Leicester, in the county of Leicester, England,have invented certain new Improvements in. Planing-Machines, of whichthe following description, in connection with the accompanying drawings,is a specification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention'relates to an improvement intended for presses and moreespecially presses in which one of the pressure memhers is made of woodor similar material which is liable to become roughened or uneven underrepetition of the pressing operation, and comprises an attachment topresses of the above type by which such inequalities or roughness of thepressure member may be removed and a smooth surface imparted thereto.

This invention is especially applicable to that class of presses of theabove type that are used for dying out sheet material, such as leather,felt, etc. Presses of this type usually have a wood cutting'bed intowhich the sharp edge of the die is forced slightly in the operation ofthe machine. It will be readily understood that sucha bed soon becomesroughened under this action of the die and must be re-surfaced.Especially is this the case when the member which acts to force the dietoward the bed has a movement substantially parallel to the surface ofthe bed in addition to its pressure applying movement which issubstantially perpendicular to such bed, as a member having these twomovements will sometimes act to force the die toward and into the bedwith a combination of these two movements, thus greatly shortening thetime within which the surface of the bed becomes too rough forsatisfactory Work.

The device of this invent-ion is also useful when the surfaces of thepressure members are not exactly parallel Whether this is due toirregularity in the mounting of one or both of said members or to otherreasons, and in such cases may be employed to bring the. said surfacesinto the desired parallel relationship.

:Hithrto it has been the custom to remove' the bed from the machine whenits surface erated by hand or power.

has become roughened or 'when for other new surface thereto. After theremoval of the bed from the machine its surface was I removed to auniform depth'xby a plane opg In cases of irregularity in the mountingof one or both of the pressure members on the machine and i in cases,therefore, in which the said bed and its cooperating pressure member arenot supported in exact parallelism, the abovemethod is incapable ofimparting, a surface to the bed which shall be exactly parallel with thesurface of the other pressure member, owing to the necessity in suchcases of removing the different portions of the surface of the bed todifferent depths.

A principal feature of this invention relates to an attachment to be.applied to presses of the above or similar types by means of which thesurface of the bed may be trued into parallelism with the acting face ofthe cooperating pressure member.

Another feature of this invention relates to a resurfacing attachment tobe applied to presses of the above or similar types in which themovement of the pressure applying member relatively to the bed may beutilized to operate the means for re-surfacing the bed and for impartingthereto a surface parallel to the movement of the said pressure applyingmember.

A further feature relates to means for causing the resurfacing means toact on different portions of the bed on successive actuations of thesaid pressure applying member,-while another feature relates to theprovision of means for reversin the movement, relatively to the bed, ofthe resurfacing means, and still another feature of the inventionrelates to the provision of means for preventing actuation of thepressure mem bers relatively to each other while the' gtrullfig orsmoothing tool is in position between t cm.

Further features of the invention relate to the provision of means for"adjusting the feeding means for the tool; as the bed is worn orsmoothed down, and for preventing injury to the feeding means should thefeed; g

Figs. 6 and 7 are details showing respectively one end of the knife anda part ofthe means for preventing vertical actuation of the swinging armwhen the attachment is-in place.

The frame of the machine is indicated at 2 and as shown supports thepresser bed 4, preferably of wood or similar material, and the hollowpost 6 onwhich the pressure member 8 is mounted to swing. into variouspositions over said-bed. By vertically reciprocating said hollow post 6as by means of sition over the bed the said member is moved to exertpressure at the place desired. For adjusting the height of the pressuremember 8, the connection 15 between the eccentric 9 and the hollow shaft6 that supports that pressure member is made adjustable as by ineans ofa rod 16 operated by a hand wheel 17.

The construction, above described, illus trates one type of ress towhich this invention-ma-y be app forms no part. of the subject-matter ofthe present application, being covered by the prior application, SerialNo. 338,014, filed October 8, 1906. r

Suitably secured to pressure member 8 is a plate 20 on which atoolcarrier 22 is mounted so as to slide longitudinallyof said member 8. Oncarrier 22 is mounted'a block 24 which preferably is pivotally attachedthereto by a pin 25 and which carries the truing knife or tool 26 whilea spring 27 mounted between said 4 block and carrier tends to hold thetool 26 with its cutting edge in position to act upon the bed 4 of themachine, the limit of such movement being determined by contact of apart of block 24 with carrier 22. Journaled in the plate. 20 is a screw30 which passes through the carrier 22 for imparting thereto movementlon-. gitudinally of the member 8. Upon the end of this screw is aratchet 'wheel 32 adapted to be operated by a reversible pawl 33. Thisied but which in itself wheel 32.- member 8 the t00l'26 or 28 will beforced pawl is seated in a'recess formed'in a pawl .carrier 35 and ispressed toward the ratchet wheel 32 by a spring 36. The stem 37 ofprovided with a head 38 upon the pawl' is that are adapted to.

which ribs 39 are formed engage recess 4 in the pawl carrier to main tamthe pawl 1n one or the otherof its adjusted positions. The pawl carrier35 oscillates about the same axis of rotation as the screw 30 and isprovided with two arms or extensions which extend into proximity tov theopposite sides of an abutment 42 which in the construction illustratedin the drawing is in the form of a ball-he2ided bolt screwed into asocket 44 supported from a clamp 45 which is attached to the table 4 bya bolt 46.

In the construction illustrated in Fig. 5, the pawl carrier 35 inaddition 'to the pawl 33 also carries a spring pressed plunger 48 seatedin a second recess in said carrier and engaging the ratchet wheel 32 toprevent rotation thereof except when moved by pawl 33. The form of toolwhich is preferably used with this attachment is indicated in Fig. 6.and as shown said tool consists of a bar cut out at the end 'to form aplaning edge.

In the form of tool illustrated in Fig. 2 one edge only is adapted toserve as a planing edge but in that form illustrated in Fig. 4 the tool28 is made double so that either end may serve as the planing'edge. Thetool carrier 29 shown in this figure is supported somewhat differentlyfrom tool carrier 22 shown in Fig. 2, but in other respects shown .inFig. 2.

"In the use of this apparatus the plate 20 is attached to the pressuremember 8 and clamp 45 is attached to the table 4, preferably to one ofthe clamping strips '50'which are employed to hold to ether the woodenportion of the table. By turning abutment 42 inits socket the height ofthe portion thereof which acts upon pawl carrier 35 may be adjustedaccording to the height of the table 4 and socket 44 may also beadjusted on its supporting clamp 45 to hold the said, abutment at thebed. These adjustments are intended to bring the head of abutment 42into position to cooperate properly with pawl carrier 35. Havingadjusted pawl 33 to move the tool carrier 22 in the direction desiredalong the pressure member 8, the operator grasps a handle 52 provided onplate 20 and swings the pressure member 8 overthe table 4. Theoscillations imparted by the operator to the pressure member 8 willbring the extensions uponpawl carrier 35 into contact with oppositefaces of abutment 42 so that the carrier will be rocked and will actuatethe ratchet Thus by swinging the pressure different distances fromact onsuccessive portions of the bed on suc- -cessive movements of said member8 so as to swung in one direction.

true or smooth said bed as maybe necessary. A reversal of the directionof rotation of the ratchet wheel and consequently a reverse] of thescrewand of the direction of motion of the tool can be obtained by revers;iug the pawl in its mountings. The tool is arranged to act upon thesurface of the bed ptily when the pressure member 8 is being On thereturn movement of pressure member 8 the block 24 which carries the toolturns about its pivot, 25. against spring 27 to permit the edge of saidtool to slide over the surface of. the bed.

' As shown, the apparatus is provided with a safety device in the formof a bent arm 545suitably attached to the plate 20 and extending underthe handle 12 of the pressure member to prevent said handle from being.depressed to cause reciprocation of said pressure'member toward the bed4 while the 25 attachment is in-place. As shown in Fig. 7, the end ofthis handle 54 is forked to embrace the rod 55 which passes into arecess in said handle 12 and the ends of the forks are beveled toprovide an adjustment for the varying spaces found between the lowersurface ofthe handle and'the surface of the pressure member 8 indifferent machines.

The provision of this curved arm 54 is important, for, as will beevident from an inspection of Fig. 1, if the press should be started bya depression of handle 12 while the attachment is in. place, themovement of pressure member 8 toward the bed 4 would probably causebreakage of the machine. As shown also, the attachment is provided witha' second safety device in the form of a spring pressed plunger 56 whichbears against a fiat surface formed upon the stem of the socket 44-.which enables the abutment 42- to turn about the axis of the stem of thesocket in case of abnormal stress being exerted upon the abutment eitherby reason of improper adjustment between said abutment spring for theand the pawl carrier 35, or by reason of the pawl carrier 35 'beingprevented by any reason from oscillating. A bolt 58 is'provided toadjust the degree of tension of the plunger 56. If desired, means, suchas an adjustingscrew 60, may be mounted in tool carrier 22, this screwhaving a point which enters between block 24 and the side of said toolcarrier 22 to turn said block on its pivot 25 against the force ofspring 27 thereby raising the end of tool 28 to an inoperative positionin cases in which it is desired to keep the said tool 'temporarily outof action .SO that the traversing effect may be obtained without actingupon the bed. By this means, the
